SAM stands for Standard
Allowed Minutes, which is a widely used term in the garment industry. SAM is a
time measurement system used to determine how much time a specific task should
take for a skilled worker to complete it. It is also a critical tool for determining
the cost of production, planning and scheduling production and establishing
production targets. In this blog post, we will explain SAM in more detail and
provide some examples of its use in the garment industry.
SAM and Time Study
SAM is calculated through
time and motion studies, which is a technique used to determine how long it
takes to complete a specific task by a skilled worker under specific
conditions. The time and motion study is based on the assumption that there is
an ideal method of performing a task, and the time it takes to complete the
task will depend on the method used.
SAM and Cost Estimation
The cost of producing a garment is determined by the time
required to complete each task, and the SAM value is used to estimate the time
required. The cost of production is calculated by multiplying the number of
minutes required to complete a task by the labour rate per minute. This
calculation provides an estimate of the labour cost required to produce a
garment.
SAM and Production Planning
The SAM value is an essential tool for production planning
and scheduling. By calculating the time required to complete each task, the
production schedule can be developed to meet the delivery date. The SAM value
is also used to determine the number of workers required to complete a specific
production run and the total production capacity.
SAM and Productivity Improvement
The SAM value is an essential tool for improving
productivity. By analyzing the time required to complete a task, the production
process can be optimized to reduce the time required. The use of new
technology, training of workers, and the adoption of new methods can all be
used to reduce the SAM value, resulting in increased productivity and reduced
costs.
Examples of SAM Calculation
Suppose a garment factory needs to produce a pair of jeans,
and the time required to complete the task is determined through a time and
motion study. The time required to complete each task is as follows:
|
Task |
Time
(in minutes) |
|
Cutting |
20 |
|
Sewing
back pocket |
3 |
|
Sewing
front pocket |
3 |
|
Sewing
inseam |
10 |
|
Sewing out
seam |
10 |
|
Sewing
waistband |
5 |
|
Total |
51 |
The SAM value for producing
a pair of jeans is calculated by adding a percentage of allowance for various
reasons such as worker fatigue, rest, and personal needs. Suppose an allowance
of 15% is added to the total time. In that case, the SAM value for producing a
pair of jeans is calculated as follows:
SAM
value = Total time x (100% + Allowance %) SAM value = 51 x (100% + 15%) SAM
value = 58.65 minutes
In conclusion, SAM is a critical tool in the garment industry used for determining the time required to complete a specific task, estimating the cost of production, planning and scheduling production, and improving productivity. The SAM value is calculated through time and motion studies, and it is used to optimize the production process to reduce the time required and increase productivity. By understanding the SAM value, garment factories can improve their efficiency, reduce their costs, and meet their production targets.
